How loud is the ear piece would these be good in a nightclub setting? Ie is the earpiece sesled enough so i could still hear people talking over music

I personally work private security in crowd situations and have been a bouncer in the past and the ear pieces would be horrible to hear with in a nightclub setting especially there is no wire that actually plugs in it is a tube that carries the sound through them and would highly recommend that you go a little bit more expensive than these and get the ones that have the plug in with wired headphones also these have horrible range especially when there’s walls in the way.
